About Marc L.

I help eCommerce and B2C teams build CRM & Lifecycle Marketing that demonstrably works: clear strategy, clean processes, and automations that run stably – because they are systematically tested, measured, and iterated.

What I support with:
• CRM/Lifecycle Audit & Strategies (Current analysis of TechStack, Journeys, Automations, Data & Tracking)
• Lifecycle Strategy & Roadmap (Prioritization by Impact/Effort)
• Implementation & Optimization of Automations (Welcome, Post-Purchase, Winback, Browse/Cart, Reactivation, etc.)
• Segmentation & Personalization (e.g., RFM/CLV logic, dynamic content)
• Testing Framework (A/B tests, hypotheses, reporting, learnings → next iteration)
• Documentation & Enablement (so teams can maintain the system cleanly in the long term)

Approach: quickly achieve clarity (Detailed Audit → Roadmap → Implementation → Iteration), pragmatic, hands-on, without overhead.
